scsi: aacraid: Fix error handling paths in aac_probe_one()
If 'scsi_host_alloc()' or 'kcalloc()' fail, 'error' is known to be 0. Set
it explicitly to -ENOMEM before branching to the error handling path.
While at it, remove 2 useless assignments to 'error'. These values are
overwridden a few lines later.
